may be operated to discharge the exhaust products oi' combustion intothe heater by ope 'ating a common forni of lever 19 within convenientreach of the ioot of the driver of the vehicle and which lever isconnected to the valve in any suitable manner, for example, by a rod 20.The hot gases or products of combustion entering the'opening 13 in theheater travel bac; and forth throughout the length of the heater in thecirouitous path indicated and discharge through an opening '14 in thebottoni oi the heater at the end opposite that having the inlet opening13. The outlet or discharge openin '14 communicates with a heaterexliaust pipe 18 which may discharge the roducts of combustion into theusual ex iaust outlet for explosive engines. The heated air dischargesthrough a grid 5' which constitutes the top of theheater and lies abovethe top horizontal air space therein. This grate or grid 5 issecured insuch position by having its edges or margins 4 inclosed between thefolds or flanges 3 of the outer box or easing of the heater. When theheater is in position the grate 5 lies `grractically ilush with thefloor of the automobile or vehicle in which it vis placed. The ninnherof air openings (i and the. size thereof depend somewhat upon the air ordinien- Asions of the heater, it being necessary under all conditions toprovide for the admission of sufficient air to heat the space Within thebody closure of the car. It will be understood that when the ear ismoving forward the passage of the air into the heated spaces 8 isincreased. 1t will be also understood that when it is desired to excludethe heat the products of combustion may be permitted to )ass through.the valve 17 without entering the heater.

llaving described my invention, I claim:

i. In a heating apparatus for autoinohilos, the eon'ibination with avehicle and the engine lfor driving the saine and its exhaust pipe, oi aheater n'io'unted transversely loelow the. 'ioor of the vehicle andconsisting of inner and outer casings which provide air space around theinterior sides und bottorn of the outer casin and a series ofopenings'in the 'liront wal ot' said outer casing communicating with theair space on one side of the heater, a series of Walls on the )ositoends of the walls of said inner shell interior of the inner Casingproviding r..

series of longitudinal passages adapted to ,11;

bc heated by the productsl o1' combustion di charging troni said engine,a grate or grid foi'n'iing the top of the heater and connuunieating withthcl air spaces thcreoil and wit; the interior of the vehicle, a valvccontrol.- ling the passage of the products olf conduis tion dischargingfrom the engine and di. rooting the saine to said heater, and au out letfrom said heater for the discharge there- Vlroni of said products ofcombustion after traversing the heat passages on thc interior ot' theheater.

2.. A heater of the character specified, comprising an outer rectangularcasing having in the front wall thereof a series of air openings, aninner rectangular casing around the outer sides and ends of whichvspaces are provided for the air entering said openings to circulatethrough, t 'ansverse ribs uniting theii'iner and outer casings andmaintaining said inner casing in a position to preserve said air spaces,said inner casing consisting of a shell the top of which is providedwith a centrally-disposed upturned longitudinal rib, a rectangular shellarranged within said inner casing and con sisting of twolongitudinalwalls the upper margins of which terminate in outwardly"lying flanges which abut with the upper portions ot' the side walls oi"said inner casing, said shell providinff a central longitudinai heat.space and site parallel longitiuliual. heat spaces which extendthroughout the length of the heater and communicate onc with thc otherby nicans of' openings in or and a` grate mounted over the air sparesformed by the inner and outer rasings and supported between theniarofins ol. the outer casing and above the longitudinal lop" rib oisaid inner casing, thc outermost side heat spaces ha\ ing openings whichcommunicate respectively with hrat inlet and exhaust pipes,substantially as specified.
